<current-plant-variety>Maybe 10-12 different plants weekly</current-plant-variety>
<GI-status>No issues</GI-status>
<preferences>None</preferences>
🤖 Output

Current Baseline

10-12 plants weekly = below microbiome-diversity threshold. Target: 30. Doable over 8-12 weeks.

30-Plant Goal Strategy

Broaden categories first:

Vegetables (aim 10-12 weekly): green leafy (spinach, kale, arugula, lettuce), cruciferous (broccoli, cauliflower, cabbage, brussels sprouts), root (carrot, beet, sweet potato), allium (onion, garlic, leek), nightshade (tomato, pepper, eggplant)

Fruits (5-7 weekly): berries (varied), citrus, apple/pear, banana, tropical (mango, pineapple), stone fruit

Legumes (3-5 weekly): black beans, chickpeas, lentils (red/green/brown), kidney beans, edamame

Whole grains (3-5 weekly): oats, quinoa, brown rice, whole wheat, barley, buckwheat

Nuts + seeds (3-5 weekly): almonds, walnuts, pumpkin seeds, chia, flax, sunflower

Herbs + spices (counts!): parsley, cilantro, basil, turmeric, ginger

Log weekly: categories × varieties. Aim 30+ distinct by week 12.

Fermented Food Addition

2-3 servings daily:

  • Plain Greek yogurt
  • Sauerkraut (raw, refrigerated)
  • Kimchi
  • Kefir
  • Kombucha (watch sugar content)
  • Miso
  • Aged cheese (small amounts)

Not supplements — actual fermented foods.

Gradual Increase Schedule

Fiber gradual is critical — too fast = bloating, gas.

  • Week 1-2: +5g fiber (1 extra serving vegetables + beans 2-3× weekly)
  • Week 3-4: +5g more (breakfast fiber upgrade — oats, fruit)
  • Week 5-8: continue building variety
  • Week 9-12: maintain 30+ plants + 30g+ fiber

IBS / GI Adaptations

If IBS or food sensitivity: slower progression. FODMAP-aware varieties. RDN consultation.

Bloating in week 1-2 normal as gut adapts. If continues past week 3, consult.
